Title: Do:cyclo-pentyl:ene-(2,2'-bis(4-alkyl-6-tert-butylphenol)) prepn. - by reacting 4-alkyl-6-tert.-butyl-phenol with dicyclopentadiene in presence of specific solvents and boron fluoride catalyst
Inventor: MUELLER ROLF DIPL ING
IPC: C07C37/14
Filed: 1979-07-02
Abstract: Prepn. is claimed of dicyclopentylene/2,21-bis (4-alkyl-6-t-butylphenols)/of formula (I) (where R1 is t-butyl and R2 is Me or Et), by reacting 1.5-2.5 moles of cpd (II) with 0.8-1.2 mole dicyclopentadiene at 20-120 degrees C in the presence of an organic solvent and BF3 or its complex as catalyst. The improvement consists in using as solvent: (a) an aromatic solvent which, under reaction conditions in presence of the catalyst, does not undergo transalkylation with the t-butyl gp. of (II) and/or (2) a non-aromatic solvent which, under the reaction conditions, does not have nucleophilic properties which strongly reduce or completely suppress the catalyst efficiency. The reaction is effected under anhydrous conditions. (I) is an antioxidant for organic substances eg natural and synthetic rubbers, polyolefins, vegetable and mineral oils etc. The process occurs in one step and gives (I) in high yields and in a non-polymerised state.

Title: Transport system utilising individual vehicles with linear drive - using transducer field to maintain small vehicle spacing for high traffic flow rate
Inventor: DONDL PETER ING GRAD
IPC: B61L23/00
Filed: 1979-11-02
Abstract: The system uses vehicles fed along transport paths without any intersection points, the traffic flow being controlled by a integrated computer system. The wave pattern distances maintaining effect of the linear motor transducer field is used to maintain the vehicles at a small spacing from one another, to enable a high traffic capacity. Pref. the speed variations for the vehicles are obtained by varying the wavelength at specific points along the transport path whilst the frequency of the electrical supply network is held constant. This wavelength variation is obtained by varying the configuration of the stator windings.

Title: Internal combustion engine inlet duct - has annular collecting ring to utilise fuel deposits on duct wall
Inventor: TIEFENBACH WILLI
IPC: F02M23/12
Filed: 1979-12-14
Abstract: The IC engine has a duct (2) carrying the air/fuel mixture from the carburettor to the engine. A ring section (6) is inserted in the duct to form an annular gap (9) where the fuel deposited on the duct (20) walls is collected. This fuel is reintroduced into the main stream through tubes (10) and a small venturi (11). The process is assisted by air introduced through tubes (15). Optionally, a spring loaded valve can be added to introduce additional air into the gap (9) under running conditions associated with a high vacuum in this area. A very uniform air/fuel mixture is obtained giving efficient combustion and good overall fuel consumption.

Title: Gas pressure regulator for central heating system - has gas inlet valve excursion determined by hot water demand
Inventor: MEIER HANS
IPC: G05D16/20
Filed: 1980-02-22
Abstract: The regulator maintains a nominal gas supply to the burner by the action of a pump and valves which are controlled by the back pressure due to the jets of the burner. A valve has its movement pre-set in both forward and reverse directions to regulate the gas inlet according to the hot water demand. Gas is admitted through an inlet via a valve. This valve is operated by a membrane which responds to the gas back-pressure. The gas flow rate is determined by the excursion of this valve which is limited by a stop. This is linked via a rod (15) to a membrane which responds to the hot water flow rate through a chamber.

Title: Crucible-less zone melting device - has coupling capacitor joining heating circuit to MOS transistors of HF generator
Inventor: KELLER WOLFGANG DR RER NAT
IPC: C30B13/20
Filed: 1980-05-20
Abstract: A crucible-less zone melting device for vertical semiconductor rods, esp. silicon rods, is equipped with a h.f. induction heating coil which forms, in conjunction with at least one parallel capacitor, an oscillatory heating circuit. This circuit is linked by a coupling capacitor to the active element of the h.f. generator. The preferred active element is a series or parallel connection of MOS-power transistors. This creates a device which can be made and operated at low cost. The h.f. source supplies a sinusoidal signal and has a good efficiency, without being affected by load changes.S The fusion zone (8) in the vertical silicon rod (6) is produced by an induction heating coil (7) in an oscillatory circuit with parallel capacitors (5) which receives its energy from a h.f. generator (10) through a coaxial cable (9). The active element is represented by two pairs of MOS-transistors (11,12,13,14) which receive a feedback signal on their gates via two coils (17,18). The drains of the transistors (11,13) are connected to the mains through a choke coil (15). A coupling capacitor (16) transmits the generator signal to the heating circuit.

Title: Measuring shaft vibrations caused by imbalances - using two sensors and two measurement speeds for static and dynamic separation
Inventor: HIMMLER GUENTHER ING GRAD
IPC: G01H1/00
Filed: 1980-11-26
Abstract: The measuring arrangement for horizontally mounted rotating bodies uses two measurement transducers operating in different measurement directions to derive values at two different rates of revolution. The measurements are unaffected by error sources such as shocks and shape factors. The arrangement can be used for balancing with the appropriate additional equipment. The shaft (1) deflections are measured at approximately null and operating rotation speeds for magnitude and direction. The difference between the values measured at the two revolution rates is used to enable separation of the static from the kinetic deflection components. The resulting components are added vectorally according to the measurement directions.

Title: Method for detecting malfunctions in an exchange circuit in telecommunications switching systems, in particular telephone switching systems
Inventor: OBERHAUSER WALTER DIPL ING
IPC: H04M3/10
Filed: 1981-02-26
Abstract: To supplement the existing devices for fault detection in the circuits of a computer-controlled telephone PABX system, individual connection phases are monitored and deviation from a pre-defined standard is registered in a counting device (Z). This applies, for example, in the absence of the signal (ZM) of a called subscriber following the requested connection of the ringing signal. If a pre-defined counting limit is reached, the set-up of a test connection to an automatically testing connection unit (TPr) is effected. Furthermore, the cases in which the switched-through connection is cleared down after the signal in a short time span beginning therewith are registered in a counting device (ZK) provided individually for each circuit. <IMAGE>

Patent DE-3116947-A1 (DE)
Title: Digital measuring arrangement for the angular position of an alternating rotatable magnetic field
Inventor: KLOTZ HERMANN DIPL ING
IPC: H03M1/00
Filed: 1981-04-29
Abstract: The invention relates to a digital measuring device for the angular position  theta  of an alternating rotatable magnetic field. In this device, the phase difference, corresponding to this angular position, between two alternating voltages is evaluated, the phase of which can be moved in opposite directions and which are obtained with the aid of an RC double bridge from two voltages, the amplitude of which corresponds to the sine and, respectively, cosine of the angle  theta . Such a measuring device is needed, for example, for measuring the position of a magnetic probe with respect to north. The invention deals with the problem of how, when a not precisely sinusoidal alternating voltage is used as exciter voltage and the use of filters then becomes necessary, these can be designed to be simple and still no drift errors need to be accepted. To achieve this, an auxiliary alternating voltage is applied alternating with the movable-phase voltages via the filters and the phase error is determined when the auxiliary alternating voltage is input. This phase error is then taken into consideration when measuring the phase difference of the alternating voltages.
